Oh! You are the best! Tnx! Its finally work! Thank You!

I try it, I put this code to function.php, but without results 🙁

code, what I put:

function my_cptui_add_post_types_to_archives( $query ) {
	// We do not want unintended consequences.
	if ( is_admin() || ! $query->is_main_query() ) {
		return;    
	}

	if ( is_category() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {

		// Replace these slugs with the post types you want to include.
		$cptui_post_types = array( 'recepty', 'Recepty' );

		$query->set(
	  		'post_type',
			array_merge(
				array( 'post' ),
				$cptui_post_types
			)
		);
	}
}
add_filter( 'pre_get_posts', 'my_cptui_add_post_types_to_archives' );

at in the end of function.php

For exaple:
My Post Type name is “Recepty”, it in chech recipes
https://sarahkopcanska.cz/kategorie/dezerty/ – it is category “Dezerty”
https://sarahkopcanska.cz/recepty/dynovka-2/ – its item in category “Dezerty” but it isn’t in the url …./kategorie/dezerty/
